Codex Seraphinianvs

Thanks to Gambols and Frolics, I've found out about the Codex Seraphinianvs. Some claim it's the weirdest book in the world. It's a tome drawn and "written" by Italian artist Luigi Serafini.
The Codex is a collection of original artwork by Italian artist Luigi Serafini, presented as a travalogue or scientific study of an alien world. Unlike such alien worlds as Darwin IV in Barlowe's Expedition, which one might find in a science fiction novel, the world in the Codex is obviously some kind of perverse reflection of our own. All of the Codex is presented entirely in an obscure alien writing. This writing, in combination with the bizarre pictures, is what finally puts the Codex in its own league for weirdness. For instance, on one page is a "Rosetta Stone" - only it just translates Codex script into another alien language.
The Web site above has images from the book and some links for more information. It seems to me to be an attempt to create a modern version of the Voynich Manuscript. You can find a few links about the Voynich Manuscript here (scroll down).
